Guinevere One
From Tardis Wiki, the free Doctor Who reference
Guinevere One was a Human-built space probe sent to explore Mars in 2006 in order to look for signs of life. En route, it was intercepted by a Sycorax spaceship and never reached its destination. Among other articles, it contained a sample of A+ blood which the Sycorax exploited. (DW: The Christmas Invasion)
